IMPROVEMENT ln'eArss.

Specification forming part of Letters Patent No. 172,930, dated February1, 1876; application filed December 10, 1875. i

pivoted bars are employed, such bars being connected together by aseries of vertical bars, and the gate thus formed is provided with acounterbalance arm or lever and weight; and

the object of my invention is to enable such gates to be folded into asmaller space than heretofore, and also to give rigidity as well aslightness to the structure; but that my invention may be fullyunderstood, 1 will describe the same in detail, by reference to thedrawings annexed, which form part ofthis specification, and in which--Figure 1 represents a front view, and Fig. 2 a cross-section, of afolding gate and parts connected therewith, constructed according to myinvention. Fig. 3 shows a front view of the gate with the parts in theposition they will assume when the gate is open.

' In each of the views similar letters of refererence are employed toindicate corresponding parts wherever'they occur. v

A and A represent the gate-posts, and B B a pair of horizontal bars,connected at one end by means of pivots c to the post A, while theirends 9 are adapted to be received within guides or stops F, carried bythepost A when the gate'is in the position of closed, as indicated bythe drawing. The horizontal bars B B are grooved or channeled, as shownat B in such manner as to form ribs b b on each of the bars B B for thepurpose of attachment thereto of the ends of the vertical bars .D, whichare pivoted alternately to the ribs 12 b of the bars B B, the alternatebars D being pivoted to the ribs b of each bar B B while theintermediate bars D are pivot-ed to the ribs b, the object of formingthe bars B B with grooves or channels B and connecting the bars Dalternately to the tront and back ribs b b, being that when the gate israised into a vertical position, so as to leave the road or passage wayG open, the bars D shall fold within the bars B B and the said bars BB,with the inclosed bars D, may fold closelytogether, thereby saving spaceand preventing the folded gate from presenting any obstruction over thepassage-way G.

The peculiar construction of the bars B B also gives great lightnessandstrength to the gate.

E is a lever-arm, connected to the pivoted end of the bar B, andprovided with a balance-weight, E, for the purpose of counterbalancingthe weight and leverage of the gate.

broadly, a counterbalanced folding gate; but What I do claim, and desireto secure by Letters Patent, is

' Acounterbnlan'ced foldin g gate, constructed with horizontal bars B Bprovided with grooves or channels B and ribs b b, and a series ofvertical bars, D, the bars D being pivoted alternately to the ribs b b,and adapted v to fold within the grooves or channels B substantially asdescribed.
